My code for checking the returned content is as follows..

Can someone please tell me what else i need to get this working. I'm using PHP.

I sugest you use the Facebook Graph API for Groups rather than trying to scrape the data you want.

It's possible that this seems to be a case of your firewall, whatever kind you are running, trying to protect you from some transaction that is required by Facebook. For Symantec Endpoint, for example, go to Network Threat Protection -> Options -> Change Settings and under Stealth Settings, remove checks from all 3 boxes. If it's a different firewall, look for some setting that might be filtering out what Facebook needs. (Symantec, at least, does warn you in the Settings box that enabling these settings may interfere with using some websites.)
